Mercedes insist they are not concerned with the minor engine problems Lewis Hamilton suffered en route to Russian Grand Prix glory.
Hamilton took the chequered flag but only after Mercedes team-mate Valtteri Bottas let him pass under order from team bosses.
The British flyer was heard complaining on his team radio that his car was delivering inconsistent power in Sochi, with Mercedes carrying out a full mechanical analysis of his engine after the race and discovering a mapping issue.
Trackside engineering director Valtteri Bottas has played down the problem and insists it will have no bearing on proceedings when the Formula 1 roadshow arrives in Japan.
“This isn’t really a concern,” he said on Mercedes’ Pure Pitwall video. “Things like this are normally down to small issues with the mapping of the engine.
“There’s certainly no concern about the hardware or whether there will be any issue going forward. But, it is an area that we will look at ahead of Suzuka next week.
“We will just make sure we get on top of it and can give him a nice, smooth power delivery.”
